[ANN ] Jupyter tools: tex2ipy and ipyaml v 0.3
by Prabhu Ramachandran Jan. 28, 2018

Jan. 28, 2018

Hi everyone, I'd like to announce new releases of tex2ipy and ipyaml on pypi. tex2ipy: https://github.com/prabhuramachandran/tex2ipy This simple tool makes it relatively easy to convert a LaTeX beamer presentation to a Jupyter/IPython notebook using RISE[1]. This version fixes some issues, works with the latest version of TexSoup and nbformat. The second tool is: ipyaml: https://github.com/prabhuramachandran/ipyaml This allows Jupyter to store notebook files as easy-to-edit YAML files. It supports both code/markdown and outputs so is entirely compatible with .ipynb files (version 4 of the notebook format). Output dumping can be disabled if needed. This package is similar to notedown and ipymd but offers complete compatibility with .ipynb files. This version works with the latest nbformat version and also reduces a little indentation to make the yaml files a little easier on the eye. cheers, Prabhu [1] https://github.com/damianavila/RISE p.s. sorry about the cross posting.

Welcome the 3.8 and 3.9 Release Manager - Łukasz Langa!
by Barry Warsaw Jan. 27, 2018

Jan. 27, 2018

As Ned just announced, Python 3.7 is very soon to enter beta 1 and thus feature freeze. I think we can all give Ned a huge round of applause for his amazing work as Release Manager for Python 3.6 and 3.7. Let’s also give him all the support he needs to make 3.7 the best version yet. As is tradition, Python release managers serve for two consecutive releases, and so with the 3.7 release branch about to be made, it’s time to announce our release manager for Python 3.8 and 3.9. By unanimous and enthusiastic consent from the Python Secret Underground (PSU, which emphatically does not exist), the Python Cabal of Former and Current Release Managers, Cardinal Ximénez, and of course the BDFL, please welcome your next release manager… Łukasz Langa! And also, happy 24th anniversary to Guido’s Python 1.0.0 announcement[1]. It’s been a fun and incredible ride, and I firmly believe that Python’s best days are ahead of us. Enjoy, -Barry [1] https://groups.google.com/forum/?hl=en#!original/comp.lang.misc/_QUzdEGFwCo…

Jan. 23, 2018

On behalf of the Python development community, I'm pleased to announce the availability of Python 3.4.8rc1 and Python 3.5.5rc1. Both Python 3.4 and 3.5 are in "security fixes only" mode. Both versions only accept security fixes, not conventional bug fixes, and both releases are source-only. You can find Python 3.4.8rc1 here: https://www.python.org/downloads/release/python-348rc1/ And you can find Python 3.5.5rc1 here: https://www.python.org/downloads/release/python-355rc1/ Happy Pythoning, //arry/

ANN: ndtypes/xnd 0.2.0b1 released
by Stefan Krah Jan. 21, 2018

Jan. 21, 2018

Hello, this is the first release (beta) of two Python modules for describing and manipulating unboxed in-memory data. ndtypes ======= ndtypes is based on the libndtypes C-library. libndtypes has four main purposes: 1) Typing a memory block (abstract type). 2) Storing the exact layout information of a memory block (concrete type). 3) Constructing the type from a close variant of the datashape type language. 3) Dynamic type checking of memory blocks by pattern-matching an abstract function signature against the types of concrete input arguments. ndtypes implements all the heavy-lifting for typing and handling memory blocks and is meant to be used as a foundation for other modules. xnd === xnd is based on the libxnd C-library and the ndtypes module. It defines and manages typed memory blocks. Because libndtypes has full layout information, the xnd memory block is a small C-struct that contains bitmaps for optional data, a linear index for addressing bitmaps, the type and the data pointer. This makes it easy to implement lightweight memory views that support the whole range of C types relevant for scientific computing. Since libndtypes uses a standard algebraic data type to store recursive type and layout information, mapping and unpacking nested Python values directly to memory is straightforward. Unless the type contains explicit pointer types like references, bytes or strings, a single, pointer-free memory block is allocated. List of xnd's features ---------------------- 1) Missing values (NA) are supported for all data. The bitmaps are Arrow compatible. 2) ndarrays with arbitrarily nested element types and optional values. 3) Ragged arrays using offset addressing with nested element types and optional values. The ragged array type is compatible with the Arrow list type. 4) Slicing and multi-dimensional indexing. Slicing and indexing returns fully typed views on the data. 5) First class tuples and records with detailed explicit alignment and packing. 6) Constructor types (Joule(float32) != Ampere(float32)). 7) Reference types for compatibility with other memory block libraries. 8) Buffer protocol support for importing other memory blocks while translating PEP-3118 format strings to datashape.
